Studies of Effect of Surfactants on Properties of Slag Cement Mortar

Compared to ordinary portland cement, the impact of surface-active agents on the strength of slag cement and hydration products had been studied, and the environmental scanning electron microscope have been used to observe the micro-morphology of the series of the hydration products. The results have shown that the strength of slag cement with surface-active agent has been markedly improved, particularly the late strength has been greatly enhanced, the hydration has been very complete, and the change of the microstructure of hydration products has also been very distinct.
